Subject: [PATCH] aes-gcm-p10: Use the correct bit to test for P10

A hwcap feature bit is passed to cpu_has_feature, resulting in testing
for CPU_FTR_MMCRA instead of the 3.1 platform revision.

Fixes: c954b252dee9 ("crypto: powerpc/p10-aes-gcm - Register modules as SIMD")
Reported-by: Nicolai Stange <nstange@...e.com>
